Description

Drift detection is not supported for AWS::Lambda::EventSourceMapping.

Other Details

Here's maybe a scenario to explain why this would be needed:

If I create an SQS EventSourceMapping for a Lambda, and then later delete and recreate that queue, the EventSourceMapping will go from ENABLED state to DISABLED state (AWS Lambda does this) and it does not switch back. Cloudformation does not detect this drift and consequently, lambda functions fail to get invoked thus breaking apps.
